This happened immediately after a reboot for updates. Immediately after I checked for more updates and there were some, meaning this bug might already be fixed. About the updates, I noticed that a few 'failed to download' but running sudo apt-get upgrade they installed fine. I don't know if this is related but it might be. This has probably happened several times, but I don't think it's a regular pattern. Running 13.10 Alpha. Otherwise seems to be pretty stable so far despite the minor bugs.
